TABULATING AND COMPUTIN ATTACHMENT FOR TYPE-WRITER MACHINES.

Application filed July 10, 1899, Serial No. 723,290.

To all whom it may concern Be it known thatI, BENJAMIN M. Dns Jannrns,citizen of the United States, re-

Hartford and State of Connecticut,.have invented certain new and usefulImprovements in Tabulating and Computing Attachments for Type-VVriterMachines, of which the following is a specification.

This invention comprises various improvements in tabulating andcomputing devices for typcwriting machines.

The tabulating device includes means for quickly setting a typewritercarriage to any point on the scale for the purpose of locating the firstfigure or letter of a line forming part of a column. The tabulatingmechanism also comprises means for setting adding devices the properdenomination, and means are provided for turning the numbered disks inaccordance with the values represented by the operated figure keys oftypewriter and added upon the computing register.

The invention further consists in various improvements in. the detailsof the computing mechanism, some of which are applicable to similarmechanisms previously invented by me, and described in Patent No.763,966 issued July 5, 190%, and application No. 702,163 filed January14, 1899.

The invention is illustrated in the accompanying drawings, in which,

Figure 1 is a plan view showing the attachment connected to a Hartfordtypewriter; Fig. 2 is a partial plan view on an enlarged scale; Fig. 3tion of the same, shown partly in section; Fig. 3 is a right sideelevation of the shifting mechanism for throwing the attachment in andout of connection with the typewriter; F1g. 3 illustrates a figure andletter type and the connection thereof with the operating keys of thetypewriter; Fig. 4 is a front elevation illustrating particularly thecomputer and carriage stop; Fig. 5 is a front view of the com nitingattachment with its operating mechanism, the power transmitting leverbeing broken away; fi is a nal front view of the computing register; 11g. 6 is a plan view of the parts Specification of Letters Patent.

13 is a plan view of the devices for setting the driver of the computingregister; Fig. 1-51: is a side view of the parts shown in Fig. 15,partly broken away; Fig. 15 is a left end view of the typewritercarriage shown in Fig. 1 and the devices supported thereon; Fig. 16 is afront view of the parts shown in Fig. 15; Fig. 17 shows in transversesection the differential gearing of the rewinding mechanism; and Fig. 18is a detail sectional view of the connections between the levers and theshaft on which they are mounted.

The invention includes an adding i'uachine or register C which in theembodiment of the invention illustrated in the accompanying drawings, isarranged at one side of the key-board of the typewriter, and a series ofoperating levers 50 adapted by means to be hereinafter described toactuate said adding machine or register.

'The invention is not-limited to use with any particular form or styleof typewriter, but is capable of application to various styles of suchmachines, all, however, including a series of letter and figure typekeys for actuating said type. a platen, and means controlled by each ofthe keys for effecting a relative step by step movement between theplaten and type. In the particular machine illustrated the escapement orkey actuated device for controlling the step by step longitudinalmovements of the platen is indicated at X X, said escapement cooperatingwith a suitable rack bar attached to the carriage in which the platen ismounted.

The operating levers 50 for the register (as shown most clearly in Figs.2, 3 and 18 are pivotally mounted on a shaft 51 ex tending transverselyof the key. board of the typewriter, each lever being vertically movableunder the lever oil" a figure key of the typewriter. there being a lever50 "for each fi ure key lever. hen a figure key lever scribed.

is depressed, the corresponding operating lever 50 rocks the shaft 51sufficiently to operate the escapement controlling the power devices bywhich the adding mechanism or register is operated. As shown in Figs. 3and 18, the levers 50 are loosely mounted upon the shaft 51, the hub ofeach lever being provided with an opening 52 into which extends a pin 53projecting from the shaft, and the levers are held fromlateral movementon the shaft by pins 51 which enter lateral grooves in the shaft, asshown in Fig. 18. respect to the openings 52 that the first partof thedownward movement of a. lever 50 does not disturb or affect the shaft.During the last part of said movement of the lever however, the lowerwall of the opening 52 in the lever engages the pin 53 and rocks theshaft sufficiently to release the escape ment as will be hereinafterexplained. The levers 50, as shown, are formed of two ,parts connectedby screws.v

Upon a shaft 54, hereinafter referred to as the escape shaft which isadjacent to and extends parallel with the shaft 51, are a series ofradial stop pins 55, one for each figure key of the typewriter. Asshown, the shaft 54: is tubular and surrounds a portion of a power shaft56, said shaft 56 be-. ing connected by a. train of gearing B with asuitable motor A, whereby it constantly tends to rotate in. onedirection. The escape shaft is adapted to be connected with said powershaft 56 through the-medium of an escape wheel 57, which is connectedwith the shaft 56 by a suitable key or feather 56", so as to rotate withand slide upon said shaft. The escape wheel is provided on each side ofits periphery with ten uniformly spaced teeth and an arm 62 on theescape shaft is adapted to be engaged by adjacentteeth on said wheelwhen the latter is moved toward the left, as will be hereinafter de-Normally when the attachment is connected with the typewriter to beoperated by the figure keys, the escape wheel-occupies the positionshown in Figs. 2 and 5 of'the drawings at the right hand end of its pathof sliding movement, in which position it is engaged by a fixed stop 58(Figs. 2 and 6), which holds said wheel and the shaft 56 and motor Astationary. A pin 59 (Figs. 2, 3* and 6) projecting from the escapeshaft 54 is normally held against a fixed stop 60 by means of a.suitable spring 61, surrounding said shaft. The spring 61 while strongenough to turn the escape shaft '54 to bring the pin 59 against the stop60 w on the motor is held stationary by the stop;o8, as above described,is sufficiently sensitive tobe readily overcome by the powe of the motorand to offerlnit little resistance to the rotation of the escape shaftby the motor in the opposite direction from which it tends The pins areso located withto turn said shaft. When the parts are in the normalinactive position but in position to be operated by the figure keys thetypewriter, the arms 62 on the escape shaft is opposite and in positionto be engaged by a tooth of the escape wheel 57 if the latter is movedto the left. I

The stop pins 55 on the escape shaft are uniformly spaced on said shaftand when the shaft is connected with the motor by the adjustment of theescape wheel 57, it will rock until one of said pins engages one of aseries of depending stop pro ections 63 on the operating levers 50. Eachlever 50 is provided with one of said projections 63 and the stop pins55 are arranged in alinement with said projections 63, but the distancebetween each of said pins 55 and its coliperating stop 63 is differentfrom that between every other pin of the series and its stop.

When the parts are in normal position the when the stop projectionactuated by the lever of the figure one key of the typewriter isdepressed, the escape shaft will move onetenth of a revolution beforethe co-acting pin 55thereon will engage the projection 63 on the lever50 actuated by said figure one key, and when the figure two key isactuated, the projection 63 on the lever 50 thereby operated will not beengaged by its coacting stop 55 until the escape shaft has moved throughtwo-tenths of a revolution, etc.

The escape wheel is shifted from engagement with the fixed stop 58 intoengagement withthe arm 62 ofthe escape shaft whenever a figure key ofthe typewriter is depressed. This movement is produced by a rock shaft641 (see Figs. 5, 5 and 11) which has one arm provided with a fork 6 fengaging a groove 65 in the hub of the escape wheel. and a second armconnected by a link 66 with an arm 66 on the shaft 51. The shaft 5'1.is,' as hereinbefore described, rocked whenever a lever 50 is rocked byits co-acting figure key lever and whenever said shaft 51 is rocked inthis manner the movement transmitted through the link 66 and rock shaft64 shifts the escape wheel 57 out of engagement with the stop 58 andinto engage ment with the arm 62 on the escape shaft. It will thusbeseen that whenever either of the levers 50 is rocked by a figure keylever,

the escape shaft 5% and power shaft 56 will be rocked through a portionof a revolution corresppnding to the value of the figure key by whichthe active lever 50 is pperated and such movement of the shaft istransmit ed to the adding mechanism by a driving gear ilt spring 68which normally holds Saidrcar end down, in which positiona lug (39 onthe lever engages a pin on shaft 51 and holds said shaft in suchposition that the levers thereon are below the paths of the figure keylevers of the typewriter, the

spring 68 being strong;- enough to overcome the springs which acttoraise the operating levers of and hold them beneath the figure keylevers to be operated thereby (see Figs. 2., 3 and. 6).

Upon the 51 a loose disk or collar 71 which is connected with the shaftby a spiral spring The disk has an arm 73 which engages a pin '74: onsaid shaft. When the spring; 68 is holding the shaft 51 in position toprevent the levers 50 from being rocked when the figure keys of theactuated. the arm 73 of the t) riter are disk or collar 1n contact withthe pin 7% on the si it til. l-V hen the key 67 at the forwarc nd of thelever 67 is depressed, to throw the attachment i to operation, the arm69 on said lever engages the arm 73 on the disk '31. thus puttin thespring, 72 under tension with a tendency to rock the shaft 51 and aidthe springs 4-9 in throwing up the operating levers 50 into engagementwith the levers of the figure keys.

W hen the attachment is disconnected from the figure key levers. theescape wheel 57, as shown in and 6. is in engagement with the arm 62 onthe escape shaft, as the rocking of the shaft 51 to move the levers 50from the position where they will be actuated by the key levers, acts toslide said escape wheel to the left on its supporting s aft; but theshaft 56 is prcventedfrom at such times by a pin 75 project em a collaron the left hand end of apement shaft 54. and bearing against :11 end ofthe lever (57. This stop pin 75 is ituatkxl above the axis of the shaft5%, (l 5% and said pin is in the nature of a crank pin which preventsthe shaft from revolving by abutting against end of lever 67. The shaftSS is therefore also locked against rotation when the attachment is disonnect d from the figure key levers. although the escape wheel o? is notenqaged by the stationary stop 58. The shaft of; extends beneath thewheels of the register C and on said "naft. as before described. is

b mounted the iriver 76 which is adapted .and also into position tointercept an arm to be shifted along the shaft to engage any one of thecarrying wheels 77 in the adding machine or register.

In using the invei.:"on as an attachment for the typewriter, for thepurpose of simultaneously adding; numbers and writing them, it isnecessary to, adjust the driver '78 to correspond with the position ofthe type writer carriage before commencing to write each number and itis essential that the driver should have a step by step move mentcorresponding to the step by step movement of the typewriter carriage,while the number is being written.

For the purpose of adjusting the driver to bring it into engagement withthe proper carrying wheel for the first figure of any number, I use akey board I) having a series of suitably marked keys 78. Each of thesekeys is mounted on the upper end of a lever 79 fulcrumed at 79 andhaving a toe 80 at its lower end. When pressure is applied to either key78, the lever 79 thereof is first rocked about its pivot '79 and the toeis moved rearwardly into position to engage a stop 8O onthe frame of theregister C and then the key board D is rocked down. as will behereinafter described. The toes 80 of the several levers 79 are ofdifferent lengths to correspond, inversely, with the 9 wheels 77 of theregister are mounted. An

arm 86 rigidly connected with one of said arms 8% is connected with arack 87 which meshes with a pinion 129 geared to the motor A and adaptedthrough inter 'cning mechanisms to rotate the carrying wheels andnumbered disks of wit) register in accordance with the various figureswritten by the typewriter when the levers 50 of the attachment are inposition to be actuated by the operation of the figure key levers. Thisis accomplishedby means of a spring which reserves the power exerted indepressing the armor lever 84. which 5 :ng is herein referred to as themotor A. Said spring will be partially wound every time the he;

board D is depressed. as will be-more fully explained hereinafter. Wheneither of the keys 78 is depressed, its toe 80 is moved into the path ofthe stop 80% as above described.

81 on a slide 82 which is mounted on a rod 82 and connected with thedriver 76 bya yoke 83 engaging a groove in the driver hub.

A link 88 connects the arm 86 with a s tor gear 89, which. gear mesheswith a 1. ion 90 on a rock shaft 91 (Figs. 7, 13 and 14). The shaft 91also carries an arm'SQ having a segmental slot 93 through which extendsa pin 94, said pin beingfixed on a l lever 95 which is pivoted to t remain frame 9B and formed therein a, curved slot through which the rockshaft- 9l. extends. From these connections it will be seen that wheneverthe key board Dis depressed it operates to rock the shaft 91 and whenthe endof the slot 93 in sand arm comes into contact with the pin 9%,thelever 95 is moved in the same direction as said arm 92.

The forward end of the lever 95 is connected by a link 97 with the slide82 which carries the driver 76. slide also carries two pawis 98 and 99,(Figs. 8, 9 and which.

cooperates with a vibrating rack 100 forming an. escapement of a typethat is con'nnon and used on some typewriters. A spring 101 theinfluence of said spring 101. The rack 100 is supported by a frame 102pivoted at 103 and having a forward extension 104 which is adapted to beengaged by an arm 105 on the shaft 51, when said shaft is rocked byeither of the leaves or by the action of the spring: 68, as hereinbeforedescribed That is, when the attachment is disconnected from thetypewriter the spring 68 will cause the shaft 51 and arm 105 to hold therack 100 above the pawl 99 and in engagement with the pawl 98 as shownin dotted lines in Fig. 8. And when the typewriter and attachment areconnected the rack will be moved into the position indicated. in dottedlines in said figure whenever a figure key lever is depressed. U

its before described the driver 76 is moved leftward on the shaft 56when either key 78 is'depressed until the too of the lever of said keyis intercepted by the arm 81.. The parts are soproportioned and theescapement, consisting of the rack and pawls 98, 99, is such that thisleftward. movement of the slide 82 will carry the driver 7'6 one step tothe left of the carrying wheel 7'? with which it should first engage.sis the key 67 is depressed, however, the rack 100 moves downward, orfalls into the position represented in full lines in 8 and by engagementwith the pawl 99 moves the slide 2 one step to theright and brings thedriver 76 into proper position. This operation all occurs before eitherof the figure keys of the typewriter is operated to print the number tobe recorded and added.

ll. provide mechanism for locating the typewriter carriage 150 at anydesired point for tabulating figures words, said mechanism alsooperating to properly locate the driver T6 for the beginning; of eachnumber. As shown, ,this mechanism is as follows: The shaft e l isprovided at its upper end to impart to the driver with a pinion 10%which meshes with a rack 10? which in. turn meshes with a pinion 108upon a shaft 109 mounted in hearings or. the upper part of thetypewriter frame adjacent the carriage. Upon the'shaft 109 are ten.radial pins 116 which with o e irregularity hereinafter noted areunnormiy s about thesha and spaced longitudinally tiereon at distancesequal to the units of the typewriter scale. Above the shaf and carriedin bearings on the typewriter carriage 150 is a shaft 111 havinga seriesof pins 112 which are radially arranged and unifori'nly spaced about itscircumference, said pins being separated longitudinally by distanceswhich equal ten units of the typewriter scale. A bevel gear 113 on theshaft 111 meshes with a segment ill l carried by a rock. shaft 115 andsaid rock shaft is also provided with an arm or blade 116 adapted to beengaged by the stems of either of series of keys 1.17. The blade 116 istapers.

and the shaft 115 inclined to row keys 17 so that the keys operate onthe blade different distances from the shaft. Each 0" said keyscorresponds to ten units on the typewriter scale and is adapted torender corresponding stop pin 112 operative. before noted, the shaft 109is provided Wlsllr ten stops corresponding with the ten units of eachdivision of the typewriter scale, and in the embodiment of the inventionillus trated, the computing device or register is adapted to registeronly seven denomina. tions. The slot Q3 in the arm 92 is provided torender the first portion of the downward motion of tl e key board Dnon-effective so far as setting of the driver is concerned and thislllllli action represented by the keys 2'8 bearing the numbers 8 and 9.is arrangement brings the zero pin llflon the shaft 109 radially veenthe s representing the venth and eighth lllllbS.

From the foregoing; it will be unde stood that when the keys 78 hearingthe numerals P or 9 a depressed, the armllfZ will not be movedsul'liciently impart any movement That is, the arm 92 calo the lever 9o.DilblG- of inoviw the distance through which i n J, I 1 1 e it is'adyusted to operati eiy p0s1t1ou the stop pins l .10 corresponding tosaid. keys without all'ectiuig5 the driver 76 of the 00111 putlng'mechanism. W hen the key hearing the numeral 1 is depressed, the arm 92y will be moved through the same distance be fore actuating the leverand then said arm and lever will move together sufficiently 76 amovement corresponding to one of the divisions on the typewriter scaleor one of the step by step in! 'cinents of to typewriter r riage.cnmilarly when either or the other Keys 18 is operated the arm 92 w l hemoved a distance greater by two (iii one of the typewriter scale than isincocdteo by the numoral of the depressed key. It will be seen that thespring 101 acts to hold the driver in position to actuate the units diskor indi-. cator of the register and that the effect of depressing thekey-board D is to move the driver in opposition to said spring,the'extent of such movement being determinedby the particular key 78which is actuated.

The typewriter carriage is located for the beginning of a number or aword at any part of the typewriter scale by depressing the key 117correspondii'ig to the section of ten units in which the number or wordis to be begun, and depressing one of the keys 78 to locate theparticular unit in the selected section of ten units. The key 7 8through the connections before described rocks the shaft 109 and locatesthe proper pin 110 in. position to engage the pin 112 which corre spondsto the depressed key 117. l' i hile' the two keys are depressed thecarriage is moved until the selected pins 110 and 112 contact. The meansby which the typewriter carriage is thus moved may vary according to theparticular typewriter to which the invention is applied, but in everyinstance such means will include devices for discon- 'necting the feedrack from the key controlled escapeinent devices. Commonly, as in themachine illustrated, such disengagement may be effected by depressing akey connect/edwith the feed rack and arranged in such relation to thekeys 117 that the operator can simultaneously actuate with one hand saidrelease key and the selected or (losired key 117, while with the otherhand the desired or required key 78 is actuated. The parts are thusadjusted to bring the first figure of the number or the lirst'lctter tobe written in the desired position. if. for instance; it is desired tobegin with the graduation 7 1 of the typewriter scale, the key 1117marked 7 and the key marked. 1 of the -key board D would be depressedand the carriage then moved until the pins 110, 112 corresponding tosaid depressed keys were in contact. in its operation the shaft 109 withits Zero pin in line with pin 112 in the seventh section would rotatepast pins representing the eighth, ninth. first, second and third unitsand stop at the fourth which is located four units to the left of thezeropin.

The register C includes a series of carrying wheels 77 and a series ofnumbered disks each bearing ten numerals. Eachof said numbered disks.except'tho-se at the ends of the series is provided with two gears 77and 77, arranged respectively at the left and right of their associateddisk. The nunioe disk at the right haul side of the provided only witha. gear 77 and t a]: has only a 77 as is :o in of this haracter.carrying wheel 77 cthe re ister 0,

register into alinement for the purpos or as shown, is provided withtwenty teeth and to one face ofeach carrying wheel is cured anadditional wheel 1 10 having ten tee h. A 5 )ring 141 operating betweent i wheel 14-0 serves to bring the bringing the figures on theseveraldisks a straight line and also to prevent the driver from beingobstructed by a slight displacement of any of the carrying wheels. Thecarrying tooth 77 on each of said wheels 77 is movable in one directionand is spring pressed radially outward to its working position, as shownin Fig. 12. When in position just before or after carrying the disk ofthe next higher order, the said displaced disk may be operated by thedriver without displacing the disk at its right such operation merelypushing said carrying tooth out of the path of said gear. in index 131,projecting from slide 82 and visible through an opening 135 in the caseof the register C, (Figs. 3 and 5), serves, to show the location of thedriver at any time.

ieferring particularly to Figs. 9 7

o, i and.

17, the train of gearing B includes an internally toothed gear 120 whichis rigid with the frame of the motor and a similar gear 121 looselysupported on the wind ing shaft 122. A pinion 123 is rigidly mounted onthe shaft 122 and a pinion meshes with said pinion and nvith the gears120 and 121. The pinion 124 has no support other tl an that furnished bythe pinion and the gears 120, 121. The gear 121 has less teeth than thegear 120 causing to gain over the latter every time the idler makes acomplete revolution of gear 120. thus giving said gear 121 a very slowmotion compared with the movement of the shaft 122. A pin 125 on thegear 121 passes during the complete winding of the motor spring from therack 87 to the arm 12b of a vertical rock shaft 127 mounted on theframe. A ratchet 128 is rigidly connected with the winding shaft 122 anda gear 129 is loosely mounted on said shaft, pawl 130 locking said gearand ratchet together in one direc tion. The gear 129 is as beforepointed out adapted to be engaged by the rack 87 connected with the keyboard D. The icy board D is in effect a lever every actuation of whichwill therefore act to turn the shaft 122, unless the rack 87 isdisengaged from said shaft, as hereinafter described. and to transmit tothe motor the power required to move all of the disks or the iputingregister that are to be operated by the depression of the figurekeys of the type writer for the number to be written. i i iien the motorspring is fully wound, pin. "25 will raise the rack 87 from engagementthe wheel 129 and when the motor spring is nearly run down said pin 127.Said shaft 127 has an arm 131 to which. is connected a rocking rod 132,said rod being adapted to pass under the end of have its parts soadjusted that the ciphers on the several disks hereof will be in linewith the openings in the register casing, and the escape wheel 57 willbe in the position shown in Figs. 5 and 6, it being understood that thespring 68 is operating'to hold the rear end of the lever 67 down andtherefore the levers 50 are below the paths of movement of the levers ofthe figure keys of the typewriter. 'llhe typewriter may be used in theordinary manner without effecting any change in the register or theposition of the escape wheel 57. If it is desired to merely use thetabulator without affecting the register, the operator, by means of thekeys 117 and 78, can readily position the stops 110 and 112 to begin thewriting at the desired point on the typewriter scale and the operationof the typewriter will not change the position of the shaft 51 or movethe escape shaft. When however it is desired to accumulate or add aseries of numbers simultaneously with the recording or-printing ofsuc'lrnurnbers by the typewriter, the operator will first position thetypewriter carriage and the driver 76 as for tabulating by manipulatingthe keys 117 and 78 and moving the typewriter carriage to the desiredposition, and will then depress the key 67. As this key is depressed theshaft 51 will be rocked to bring the levers 50 thereon into engagementwith the levers of the figure keys of the typewriter and the escapewheel, 57 will be shifted to its right hand position where it is engagedby the stop 58, as shown in Fig. 2. While the key 67 is held depressed,the operator will strike the figure keys corresponding to the number tobe written and added, and as each of said figure keys is depressed thecorresponding lever 50 will be moved, and through the turning of theshaft 51 the escape wheel 57 will be shifted into engagement with thearm 62 on the escape shaft 54;, and the latter under the power of themotor spring will be turned until the stop 55 thereon comes against thestop 63 of the operadepressed through the action of the rack 100 andpawls 98, 99, 011 the slide 82. As each figure key rises the escapewheel 57 is returned to its right hand position into engagement with thestop 58, but is instantly shifted to the left into engagement with thearm 62 when the key representing a following figure is actuated. Whenthe desired number has been written and added the operator, by releasingthe key 67 permits the spring 68 to return the parts to the posi tion inwhich the attachment is disconnected from the typewriter, in whichposition the escape wheel 57 is in engagement with the arm 62 on theescape shaft and said wheel and shaft 56 are held from turning by theengagement of the pin with the rear end of the lever 67.
